Respiratory infections as well as infections of certain glands can be a cause of excessive saliva, according to the National Library of Medicine. Children with a cold, influenza or nasal allergies may have excessive saliva and drool.

Diseases that affect the pharynx, esophagus, and stomach can also stimulate excessive production of saliva.
